OIL-SEPARATOR.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 14, 1905. Serial No. 245,584- I To all whomit may concern:

Be it known that we, J OHN B. BERRYMAN and JOHN E. RoLLrNs, bothcitizens of the United States, residing at Chicago, in the State ofIllinois, have invented certain new and useful Improvements inOil-Separators, of which the following is a specification.

Our invention relates to apparatus for separating oil from steam, andparticularly to separators of the horizontal type using a baffle platefor the deposit of the suspended globules of liquid, and means forcleaning such plates. The objects of the invention are, to improve theefficiency of the baffle plate in such separators; to provide improvedmeans for cleaning the separator baflle plate; to provide apparatuswhich can be alternately used for keeping the baffle plate moist and forcleaning oil from the same; to prevent the taking up oi oil which may bedeposited in the inlet pipe of the separator; to prevent the outgoingcurrent of steam from picking up the deposited oil or water, and togenerally improve the structure and operation of separators and meansfor cleaning the same. These objects and other advantages which willhereinafter appear, we attain by means of the construction illustratedin preierred forms in the accompanying drawing, wherein Figure 1 is aview of the entire apparatus showing the separator in vertical sectionand a side elevation of the baffle plate therein;

Figure 2 is a side elevation of the separator casing looking in adirection at right angles to plane of Figure 1, and

Figure 3 is a central vertical section through the separator taken atright angles to the plane of Figure 1.

While our invention as here shown and described is especially adaptedfor taking oil out of exhaust steam, it will be understood that it isequally useful for removing suspended globules of any fluid from anygaseous substance. In such apparatus the oil deposited upon the baffleplate frequently carbonizes and forms a smooth enamel on the plate,which very materially reduces the eiliciency or in the course of timeentirely destroys the utility of the plate. It is very inconvenient toform the separator so as to remove the baffle plate for the purpose ofcleaning, and is equally as diilicult to clean it when in place.Furthermore, such apparatus works much better when the exhaust steam issupersaturated and the baffle plate is kept Wet, as this increases theprecipitation of oil thereon. To meet the requirements, we have provideda separator casing 4 having the steam inlet 5 and the outlet 6 and awell or receiver below which empties through an outlet 9 to carry offthe precipitated water and oil. The casing 4 contains a baffle plate 7which is provided on the side facing the incoming current of steam witha series of ribs or corrugations 8, which are preferably arranged at anangle with the vertical so as to provide suificient drainage and at thesame time cause the current of steam to cross the same, and therebyprevent the steam from picking up the globules of oil or water on theplate.

In thevordinary working of the device water is introduced into the pipe10, which ends in a perforated nozzle 11 arranged along the top of thebaflle plate 7, as shown in Figure 1, and by injecting cold water uponthe baffle plate it keeps it wet and supersaturates the steam toincrease the efiiciency of the device. The water pipe 10 is closed by acock l2 and this pipe is also connected with a supplementary pipe 13,closed by the cock l4, and receiving from the pump 15 a cleansing fluidwhich is pumped through the pipe 16 from the reservoir tank 17, the pumpbeing a steam or hand pump, as may be desired.

From Figure 3 it will be seen that in the separator casing we haveprovided a depending guard ring or flange 18 which atthe bottom has aforwardly turned portion and is placed in such position as to cause anyoil which may collect in the bottom of the incoming pipe to flow in anddrop into the well without coming in contact with the steam deflectedfrom the baffie plate 7.

From the above description it will be understood that in operation theexhaust steam containing the sus pended oil enters through the inlet 5and strikes the baiiie plate 7 depositing the oil thereon, when it risesaround the dome of the casing 4 and escapes through the opening 6, whilethe oil and precipitated water drains down naturally along thecorrugations and into the bottom of the casing and escapes through thepipe 9. During this operation water is allowed to flow into the pipe 10and is projected as spray upon the plate by the perforated nozzle 11.When the plate becomes caked with oil or otherwise obstructed it may becleaned by closing the cock 12, opening the cock 14, and starting thepump 15, which will force in through the perforated nozzle 11 anydesired cleansing fluid which is stored in the tank 17. The nozzle 11projects the cleaning fluid forcibly against all parts of the baflieplate, and thus cleans the plate without taking it out of the casing.When desired the bottom plate on the casing 4 may be removed forinspection or to clean with a brush, but ordinarily this will not benecessary, as the solution will readily remove the oil deposited uponthe plate. Other advantages of the design will readily occur to thosefamiliar with the art.

Having thus described our invention and illustrated its use, what weclaim as new and desire to secure by Letters Patent, is the following:

1. In an oil separator the combination of an inclosing casing, a bailleplate therein, means for projecting water upon said baflle plate andmeans for projecting an additional cleansing substance, thereon toaugment the cleansing effect of the water substantially as described.

2. In an oil separator, the combination of an inclosing casing, a battleplate therein, means for projecting water upon said baflle plate, meansfor holding a supply of another cleansing substance, together withconnections for introducing the last mentioned cleansing substancethrough the water connection, substantially as described.

3. In oil separators the combination with the separator and baille platetherein, of the perforated pipe 11 connected to the water pipe, and thefeed pipe 13 also connected with the perforated pipe 11" and means toforcibly inject cleansing fluid therein when the Water supply is out01f, substantially as described.

4. In an oil separator the combination with a baflle plate and a supplyof cleansing fluid, oi the pump 15 and l the injecting pipe 13, waterpipe 10 with nozzle 11, and the cocks on said two pipes, whereby wateror cleansing fluid may be alternately introduced upon the baflle plateby the perforated nozzle 11, substantially as described.

5. In an oil separator the combination of an inelosing casing, a baflleplate therein, means for projecting water upon said ballie plate, and apump for introducing an additional cleansing fluid into the water pipefor supplementing the action of the water substantially as described.

6. In combination in an oil separator a casing having inlet and outletpassages, a baille plate therein, and a guard ring or flange extendingaround the lower portion of the casing intermediate said baifie plateand inlet passage, and having its lower edge spaced above the floor ofthe casing to provide a passage from one side of the ring or flange tothe other side thereof.

' In testimony we have hereunto signed our names in the presence of thetwo subscribed witnesses.
